My very first cavity

So I called the University's Dental School Clinic this morning. The voicemail recording said that due to the hospital's high call volume, they will return calls within 8 business days. At first I thought about waiting for the return call, remaining optimistic about the 8 day call return. At the last minute, I decided to visit the hospital and make an appointment in person. (Anschutz medical center is built like a University campus... buildings everywhere) I arrive at the Dental clinic and I approach the lady at the help desk in order to see whether i can schedule an appointment. She tells me that the school isn't' accepting new patients until the end of the year and that I should go to the Emergency clinic if I couldn't wait. It took a second for me to think about it... but the "good" side of my mouth was becoming raw from the overuse & my tooth wasn't getting anybetter. I take her advice and appoint the Emergency Dental clinic check-in desk at 2:20... they take their last patients back at 2:30. I was "lucky" because the place was not busy (which rarely happens there).. so they admitted me. So the residency student runs a number of tests on me. I tell her that my tooth hurts when I brush it with a toothbrush & when I eat. All her tests come back negative, except for the sensitivity test. She couldn't find anything abnormal on the xray. She calls in the real Dr. and he realizes that I have a hidden, deep pocket cavity (my very first cavity!). It was hidden under some sealant that I have placed on my tooth years ago. He said that I was very close to my nerve and if I had waited longer... there would've been a huge possibility of needing a root canal. They prep me for a filling and he tells me that since they're not busy, they could hook me up with a permanent tooth filling. The Dental ER usually gives out temporary fillings since they're an ER. This was a good thing b/c i didn't have to wait to make an appointment with some other person and spend more $$ on an outpatient Dental visit. My mouth is numb.. i have delicious mexican food waiting to be eaten...  I cannot wait to eat food using both sides of my mouth again!
